Suntrio Plus Series
4.3.2 Installation Position
Do not expose the inverter to direct solar irradiation as this could cause power derating due to
overheating.The ambient temperature should be between -25°C ~ +60°C (-13° F ~ 140° F)
to ensure optimum operation.Choose locations with sufficient air exchange. Ensure additional
ventilation,when necessary.
To make sure the installation spot is suitably ventilated, if multiple SAJ grid-tie solar inverters
are installed in the same area, the following safety clearance in Figure4.2 shall be followed for
30CM
appropriate ventilation conditions.

② By connecting the internet through a Wi-Fi module and uploading the data of the
inverter to server, users can monitor the operational information of the inverter by
web version web portal or mobile APP (please download the mobile APP from
SAJ’s official website) remotely.
③ Connecting the inverter to computer by nine-serial port cable, the operational
information of the inverter can be read by the appropriate computer software.
④ Users can apply a Modbus protocol through RS485 together with an SAJ Logger
to monitor the data of the inverter. For detailed operation please refer to the SAJ
Logger User Manual.

·Check the volt of the grid
·Check the connection between the inverter and the grid.
·Check the settings of the on-grid standards of the inverter.
·If the volt of the grid is higher than the volt regulated by local grid,
please inquire the local grid workers whether they can adjust the volt
at the feed point or change the value of the regulated volt.
·If the volt of the grid is in regulated range as allowed and LCD still in
this error, please contact your distributor or phone SAJ.
